Oh my goodness I thought we'd made this image large enough the compression wouldn't be an issue but it appears we were wrooooong!!

how is it possible to fuck up image compression this bad. the image is 564x522

Anyway. Unrelated image compression joke: "My new super-efficient image format will work by storing every possible pixel combination to a dictionary file, and then you just provide a single number to select which image!”

also genuinely does anyone know how to avoid compression like this? cuz it always seems to do so for my art regardless of image size

I think there is/was the concern that writing to image from compute may cause the image to transition into a decompressed state (e.g. on some amd chips writing from compute disables delta color compression). gpuopen.com/learn/dcc-ov...
Getting the Most Out of Delta Color Compression - AMD GPUOpen
DCC is a domain-specific compression that tries to take advantage of data coherence. It’s lossless, and adapted for 3D rendering. The key idea is to process whole blocks instead of individual pixels.

i am a workflow enjoyer and i'm addicted to astrophotography's various workflows, all of which run through a half dozen niche freeware programs i've never heard of before
an incredible picture of the sun taken yesterday, a roiling orange orb with several flares and cool spots visible across it OP's explanation of his workflow, as follows: –]Pelo_Telescopio[S] 3 points 14 hours ago Like this. The planetary camera makes a film. In this case, there were 20 seconds of footage generating 475 frames using SharpCapture software. A processing program (autostakker), through a stack algorithm, aligns the 25% best frames to generate a single image. It then goes through another program (IMPPG) that performs deconvolution (recovers part of the signal lost in the image compression process). And finally the post processing in the Affinity software. Where fine details are improved and color is added. It takes a little work at first but once you get the hang of it it gets easier. All are free software.

Look what just arrived! I'll get a rip of this ready soon. In the meantime, here's some comparison shots of EP1 DVD VOB vs Blu-ray M2TS. Uncompressed DVD vs Blu-Ray!
slow.pics/c/e8vplnxe

Check out the alt text for my detailed thoughts/review of the transfer itself.
Sukeban Deka II on Blu-ray is presented in 1080p MPEG-4 AVC. The overall image quality represents a big improvement over the original DVDs, though not without reservations. The transfer exhibits far cleaner and sharper visuals, with nearly all dirt, scratches, and splice marks removed. Contrast is stronger, and colors are more vivid, though with a slightly cooler color timing compared to the DVDs. Black levels are solid, avoiding any clipping. Fine detail such as faces, clothes, and set textures shows a distinct uptick in sharpness over the DVDs. Sadly, DNR/digital noise reduction is applied, which leaves the image not looking as filmic as the DVDs, and with some occasional waxy artifacts. Although some grain remains, the ever-present film texture seen in Ep01-20 in ToeiCh has been dialed back. Edge enhancement is faintly visible in a few shots. No compression issues such as macroblocking or banding seem to be present. Source stability is very good overall, save for some mild shaking during freeze-frame shots and a few light scratches that escape cleanup. Shots with optical transitions, optical credits, and dissolves appear inherently softer, any use of recycled footage looks somewhat rougher than the rest. While not fully grainy, the transfer itself still has a lot of granular detail intact and a very crisp appearance. Compared to Sukeban Deka I on Bluray, which also suffers from a similar DNR impletentation, Sukeban Deka II feels more refined and more film-like with more granular detail preserved amid the DNR. Overall, I'd say it's still a big enough upgrade from the DVDs even with its DNR imperfections.

gif is an image compression format, it doesn't have to be animated (there's animated png and other formats too). Today we learned.

That said, bluesky converts to jpeg, so I guess,

forgot to use my own 🍜 tag to put it in my cooking feed. oh well i just dumped a bunch of red beans in so it's an excuse for another "glamour" shot (grumpily downsampled to 800x600 since bsky is being a bitch about image compression)

Part 3 of MDN’s Image formats series is here! 🖼️

We’ve covered color models & encoders. Now it’s time to compare real codecs and compression tools. Learn how to measure “image quality” the right way.

Image compression involves countless trade-offs between quality, size, and speed. In this final part of the series, we experiment with codecs, metrics, and tools to find practical ways to balance efficiency and visual fidelity.

that's some crunch on the compression bluesky, have a detail shot folks!

Was playing Sonic Origins again recently because I got the itch to. Then I remembered hearing that in one of the Sonic 2 that Tails could carry you in the water. I decided to try it in S3&K, and was greeted by this. I don’t think I’ve EVER seen this sprite. I was expecting it to just…do nothing tbh
Screenshot of S3&K in Sonic Origins Plus, showing Tails holding onto Amy underwater in Hydro City Zone. Screenshot of S3&K in Sonic Origins Plus, showing Tails holding onto Amy underwater in Hydro City Zone, but zoomed in to show the character sprites better in case of compression making it harder to see in the first image.

That hero image sketch went from about 400kb to 13kb with barely any perceivable difference. Modern image compression is bananas.

I'm dead-tired but I tried modifying the image size & text, and hopefully the compression quality isn't bonkers

Galileo SSI image. Full resolution green frame combined with 1/2 resolution red and violet frames and processed to approximate natural color. As with the majority of Galileo images, this observation employed a lossy compression scheme due to the high gain antenna problem so compression artifacts are abundant. C9ISSRFMON02.
